(o1.v ss-fzss) '56 Claims. .l

'The present invention relates to a wrapping machine, particularly onethat automatically wraps .paper Yabout a candy bar Aandfglues thewrapping paper-at the proper places so that when each bar leaves the'machine it iscompletely wrapped Aand ready to be packed -into'l boxesfor shipment. The candy bars Acontemplated-for the present'machinehavesoft or medium, hardcenters 'and yare coated with chocolate. Thus `theproducts ,upon'which the present machine performsitsnumerous'wrappingoperations are fragile togthe extent that they can be crushedordistortedin's'hape-and the chocolate coatingv can very easily bebroken or marredif Ythe bars are roughly handledv-or too much Lforce'isapplied to the bars while i 'the machine is performingv its numerous`operations. f

-'I-husit is Ian objectof Ythe .present invention to provide va machinethat-'rapidlyand neatly wraps candy `hars without in t any lwaycrushingor. distorting the shapeof .thelbarsand withoutcracking or in`any way marring the f chocolate coating.

'The ymachine embodyingthe -invention is .intended to operate at .high,rates l of. speed,` turning outa relativelylargeflnumber of completelywrapped vbars. and it is required that; such.; a machine besubstantially foolproof initsoperation because even a `.fraction of aseconds obstruction-by Aone ofthe bars while itis passing throughthemachine will causeotherfbarsto pile upsoas'towcompletely shut downthe -machne andthe production vline in which the machine is operating.vNormallythe problem of cleaning `a machine following such a piling upof :candy bars, is bcth-diicultand tedi ous, 'in most-.instancesrequiring the use of a. considerable amount of high temperature'steam-in order: torexnove the candy from the machine mechanisms. AWhile thissteam is useful in melting the candyA and thuscleaningup the machine,italso dries up the oil in the bearings. and thus over a period of timemay result in actual damage tothe'workingparts of the machine.

Itis another object of the present invention to provide a machine thatis relatively simple-in its construction and .is open and relativelyfree of confiplexv mechanisms and crowded vparts, vin .the regions,Where the piling up of vthe Ycandybars is most likely. Vto .occult At'the same vtime 4thema-- chine provides an automatic safety shut-olfdevice thatimmediatelydiscontinues the machine operation when a pile upof the candyv occurs.

HAll of the foregoing constitute some of the principal :objects andadvantages'of ,the present in-y vention,`others of whichwillsbecome-apparent from 'the following description and from thedrawings; in which:

VTwo embodiments of the present invention are illustrated herein for thepurpose of explaining the present invention. It is recognized, however,that the specific embodiments may be modified without departing from theintended scope of the invention. y

For an understanding of the present invention reference is first invitedto Figs. 1 and 2.

of the drawings where the portion of the machine forming the subjectmatter of the present machine is diagrammatically illustrated. Thismachine is generally indicated at 40, and it has a feeding end at theright hand side of the machine as viewed in Fig. 1 and a discharge endat the left hand side of the machine. Candy bars indicated at 4| are fedby means of a conveyor 42 into the machine at the feeding end thereof.Also at the feed end of the machine is fed a continuous strip ofWrapping paper shown at 43 that is fed from a supply (not shown) thatmost conveniently may be in the form of a large roll (also not shown)mounted directly on the machine. This wrapping paper 43 is fed over apaper feed roller 3l (Fig. 2) after having had glue applied along itsside edges at appropriate locations for forming a paper tube describedhereinafter. Guide rollers 38 and 39 help in the paper feed opera-tion.This paper 43 is fed into a folder generally indicated at 44 that may beof any conventional type suitable for wrapping candy bars. A feedingplatform 45 is disposed at the entrance or feeding end of folder 44 andthe belt conveyor 42 discharges the candy bars 4| directly onto thisfeeding platform 45. Mounted directly below the feeding platform 45 andthe folder 44 is an endless chain conveyor 46 that operates about a pairof spaced sprocket wheels 41. The feeding platform 45 extends beneaththe entrance end of the folder 44 and forms the bottom wall thereofthroughout the remainder of the length of the folder.

As best shown in Fig. 1 this feeding platform 45 and bottom wall of thefolder 44 is provided with a longitudinally extending slot orperforation 48 that extends throughout the entire distance between thesprocket wheels 41 and is disposed directly above the chain conveyor 46.This chain conveyor 46 is provided with a plurality of pusher lugs 49that are adapted to project through the aperture 48 to a position abovethe platform 45. Thus when the candy bars 4| are fed onto the feedingplatform 45 by conveyor belt 42 they are placed in the path of the lugs49 so that as the chain conveyor 46 moves between sprocket wheels 41 ina counterclockwise direction as viewed in Fig. 2 of the drawings, eachlug 49 engages the end of a candy bar 4| and pushes it into and throughthe folder 44 to the end of the travel of the conveyor chain 46.

While the candy bar 4I is thus being fed into the folder 44 the wrappingpaper 43 is also being fed into the folder 44. The manner in which thiswrapping paper 43 is wrapped around the sides and underneath the candybars by folder 44 and the actual structure of the folder 44 forms nopart of the present invention and in fact is very conventional inwrapping machines for candy bars and the like. The paper 43 is actuallyfed over the top of ea-ch candy bar 4| and as the bar 4| and the paperprogresses through the folder 44 the paper is brought down around bothsides of the candy bars by means of plows indicated at 5| in Fig. 5 andthe paper is finally folded underneath the bars to the position shown inFig. 4. Thus when the candy bars reach the discharge end of folder 44they are completely enclosed in a tube-like member indicated at 43a inFig. 4 that is formed by the wrapping paper 43. This tube 43a of paper43 with its contents is then conveyed in the direction of the arrowindicated at A in Fig. 2 by means ofconveyor belts 52 disposed on bothsides of the paper tube 43a toward thealefthand end of the machineasfviewejdzin Thewrapping paper d3 'as itis vfirst 'being vfed into the.machine at the right hand end asf'viewed in Fig. lis caused to pass overa-set of glue applicators (not shown) of a conventional v.typetha-tapplies a longitudinal strip 53 of glue` alongyone,

edgeof the paper atspaced intervals and a pair of transverse strips ofglue, thezstrips being spa-ced apart in distance greater than,theflength of each candy bar. :This application;V of -glue again .isconventional practice in machines of this type f. so that the manner ofapplyingftheglue and thestructural equipment used to accomplish v thisis neither shown norv described herein. The purpose of thelongitudinal'strips'53of glue indicated in broken lines in Fig. 1 is toeffect aseal of the wrapping paper. underneath the candy bars to formthe closed tube .43a shown in Fig-4. The

purpose of the transverse pairs of glue .strips 54v VAi-,the cut-offpoint indicated in Fig. 1.of.,the.

drawings there is provided a cut-off and crimping roller 55 that isdisposed horizontally above theline of travel of the candy bars throughthe machine. Directly .below the cut-.off roller 55 is an vanvil roller55. As. shown in Fig. 2 the tube 43a of paper containing the candy bars.4i passes between the cut-olf roller. 55 andthe anvil Aroller 56. Onceagainboth the cut-.olf roller and the anvil `roller are veryconventionalv and per sedo not constitute the present invention.In-.making the present disclosure it will suffice to point out thatthef-cut-ofroller 55 is mounted to rotate in thedirection indicated by.the .arrow B in Fig. 9 and'is provided with a cut-off member or knife51, on each side. of which is disposed a crimperr 58. `The anvil roller.56 is likewise mounted to rotate about a horizontal axis and isprovided with an anvi155. on each side of which is mounted a crimper 50that complements the corresponding crimper 58 on the cutter roller 55.

Just adjacent to the cut-off roller 55 on the feedside thereof as bestshown in Figs. r1r and'9 is a pair of tucker rollers 5l, eachof ,whichis mounted to rotate about a vertical axis on an the. structureV andfunction of the tucker rollers.

6 [mounted on arms 52 are conventional and well known, it would onlyunnecessarily complicate the present descrip-tionl to show more of thestructure that supports-and operates them. It should be stated, however,that duringv the Vperiodeach of the candy'barslil is passingbetweenthetucker This latter` rollers` 5|, these tucker rollers are-spreadapart so as not-to engage and damage the sides of the'bars. This isaccomplished by suitable-camA means that operates intimedrelationshipwith the feed ofthe tube 43a of paper containing the candyAbars Vil i The vcontinuous tube 53a is fed,.as-previous1y mentioned,between the cutter roller 55and the anvil roller 55 and: from fthedischarge: side of theselast mentioned rollers the tube; Maris; fedibetween .s a. pair fof spaced pull .discs L63. .I'Ilhe structure andfunction .of kthese pull discs Vwill be described hereinafter morecompletely. lIt" should be understood, however, at .this -time that thecontinuous.tubel3c,` of 'wrapping paper'containingy the-spacedcandylbars 4l vis .advanced between Hthe pull. discs .63v approximatelyto the position shownin Fig. 1 where the specific candy bar Ala .is.shovvnwith the last .portion-only of the candy,4barstillremaining.between the pull discs 63. 'Itis Vnot until thepapertube has reached this lastmentionediposition that the first cut-off ismade,y toisever the rst candy barila with its portionof the wrapper fromthe remainderof the tube 43a. The objectof the pull discs 63 is toeifectfa. constant pull. on the .wrapper that surrouhdsthe firstcandybar 41a, .during theacutting operationand .then immediatelyfollowing `this cutting. operation the pull discs 63 release the barfilaithat hasjustbeen .cut off. vAt this .time such` bar is disposed enaconveyor belt 64 shownv in Fig-..52 that operates-,about a ypairfofspaced pulleys 55 and moves in the direction in which the candy ismoving. as yshown by arrow A in Fig. 2. `The speed-of movementof thisconveyor belt 6dv is greater than the speed of travel of the tube 43a sotha-tiassoon as the rst candy bar lila. with its Y wrapper isseveredfrom the continuous tube 43a it :movesaway from the advancing edge ofthe next bar until: bar 41a reaches a stop member generally indicatedat.66 in Figs. 1 and 2. This stop, member ,which vwill .be described morein detail-hereinafter brings the severed bar la to anabrupt state ofrest .and this position is-the end point of travel in the directioncorresponding fromright to leftin Figs. 1 and 2. Each of the severedbars is then moved-in a transverse direc-l tion indicated by the arrow Cin Fig. 1 so that from this pointoneach bar is travelling with its side.edge serving as its leading edge. The function ofthe remainder of themachine is to fold the-.ends of the .wrapper down and under each candybar and to cement or glue these ends tothe underneath face .of theWrapper.

All the various parts' and mechanisms that cooperateto performthevarious steps and operations just described'are supportedon a machineframe that includes a pair of spaced upright walls 5l and 58 (see Figs.6 and 7). As best yshown in Fig. 6 a supporting wall 69 extends inwardlyfrom wall 61 and supported on this inwardly extending wall 69 isa pulldisc assembly generally indicated at 15 of which the pull discs 63 forma part. Referring to Figs. 9 and l0 the pull disc assembly Iii includesa pair of C-frame members 'lia and 1lb mounted respectively on shafts12a and v12b. A machine screwv or the like 'i3 secures the C-frame 'Haor 'Hb as the case maybe to its respective shaft. The shafts 12a and 12bin turn are held in corresponding apertures 14a and 'Mb respectively, inthe wall 69 and project through the wall 59 and beyond the `oppoture 'maand Mb carryingy with it the -arm 15 on'` one of` its ends and theC-frame 'Ha or'll'bfonits other end.

As vbest shown in Figs. 9 and l0 each of the C-'frames la and '1lb hasrotatably mounted therein a vertical shaft 'l1 on the upper end ofeachof'which is mounted onev of the pull discs-63?.

Eachfof these pull discs4` G3i i'sfprovifde'd onits Each of theshaftsperipheral surface with .a pad portion. 18 -of sponge rubber orthe like. A'Ihe lowermost end of each shaft 11 is journalled in itscorresponding C-frame 1|a or 1lb.

Mounted-between the spaced C-frarnes 1Ia and 1lb and-securedlto wall 69is an intermediate frame 19 in which are journalled two verticallydisposed shafts 80 and 8|, as best shown in Figs. and 11. Mounted onshaft 80 is a gear 82 and on shaft 8| is a gear 83. Similarly mounted onone of the shafts 11 (see Figs. 10 and 11) is a gear 84 and ontheothershaft 11'is a gear 85.

The two gears 82 and 84 are in meshing engagement and gears 83 and 85are likewise disposed in meshing engagement. Similarly gears 82 and 83that are mounted on shafts 80 and 8| respectively,l are disposed inmeshing engagement. Mounted on the lower end of shaft 8| as best shownin Figs. 9 and 11 is a bevelled gear 86 and adjacent to the lower end ofthis bevelled gear is a horizontally disposed shaft 81 that isjournalled in the wall 69. On one end of this shaft 81 is a bevelledgear 88that isin meshing engagement with the bevelled gear 86 and theother end of this shaft 81 is provided with a bevelled gear .89.

Again referring to Figs. 9 and l0V a bracket 90 is mounted on the wall69 and journalled in this bracket 90 is a shaft 9|. On one end of theshaft 9| is mounted a bevelled gear 92 that is disposed in meshingengagement with the previously mentioned gear 89. A sprocket Vwheel 93is mounted on the other end of this shaft 9| and as will hereinafter bedescribed power is imparted to rotate the sprocket wheel 93, which inturn rotates shaftv 8| (Fig. 10) through shaft 9|". bevelled gears 92and 89, shaft 81 and bevelled gears 88 and 86 (Fig. 9). This rotation ofshaft 8| in turn causes rotation of shafts 11 and 80 through gear'pinions 83; 85 and 83, 82. The rotation of gear 82 in turn causesrotation of the adjacent shaft 11 through gear 84. Thus both of theshafts 11 are caused to rotate, thus rotating thepull discs 63.

Also mounted on the bracket 90 (see Figs. 9 to llinclusive) is a leverarm 94 that is fulcrumed on a shaft 95 which in turn is held in anaperture 96 in bracket 90. The shaft 95 projects beyond the bracket 90and a Cotter pin 91 is passed through an aperture in the projecting endof the shaft. Similarly the other end of shaft 95 projects beyond thearm 94 and a Cotter pin 98 is passed through an aperture in this lastmentioned projecting end of shaft 95. The lowermost free end of leverarm 94 is provided with a camfollower roller 99 and the other free endof the lever arm 94 is connected through a link 94a in pivotingrelationship as at |00 (see Fig.v l1) to one end of'an actuating armI0|. This actuating arm IOI is fulcrumed on a pin |02 and is held inplace by a suitable Cotter pin |03. The opposite end of thev actuatingarm I0| is provided at |04 with an arcuate bearing surface that engagesone end of each vof the arms 15. As previously mentioned these arms 15are mounted on shafts 12, each of which shaft in turn carries one of theC-frame supports 1Ia and 1lb. As the lever arm 94 teeters or rocks aboutits fulcrumed shaft 95, it causes the-actuating arm |0I (Fig. 11) torock about its shaft |02 and hence rocks arms 15 with their respectiveshafts 12. The rocking of these shafts 12 causes vertical shafts v11 tomove laterally awayfrom and towardA each other and thus similarly movesthe pull `discs 63 alternately away from and toward the candy-bar 4|that is 8. passing therebetween. A tension' spring |05 is'v securedbetween upstanding bosses |06 that are mounted on each ofthe C-framemembers 1Ia and 1Ib (see Figs. 9 to 11 inclusive). The actuation oflever arm 94 is effected by a 4cam |01 mounted on a drive shaft |08 thatforms the main drive shaft of the machine and is best shown in Figs. 6,7 and 19.' The cam follower 99 (Fig. 9) rides on the surface of Cam |01.

Againreferring to Figs. 6 and 9 after a candy bar has been severed fromthe long tube 43a of wrapping paper, it is deposited as previouslymentioned on the belt conveyor 64. The pulleys ordrums 65 about whichthis belt 64 operates are mounted on shafts 65a, which in turn arejournalled at their opposite ends in plates or frame members I 09. Theseplates |09 in turn are' fastened by some suitable means such as bolts||0 and `I|| (see Fig. 9) to the frame of the machine. This entireassembly can be raised and lowered by virtue of slots IIZ that areprovided inthe plates |09. The power for driving the belt 64 is impartedto one of the shafts 65a through a sprocket wheel ||3 that is mounted onthe shaft 65a. As previously men-'- tioned the conveyor belt 64 moveseach severed candy bar with its wrapping to a stop generally indicatedat 66. This stop member is mounted on a block I4 which in turn issecured to a bracket ||5 that is secured to one of the machine framewalls. The stop member comprises upper and lower jaw-like members ||6and II1 respectively, that are firmly held together by means of a screw||8 Vthat passes into the block II4. Jaws ||6 and II1 are ared as atIISa and |I1a respectively, so that as the candy bar 4| strikes the stopmember the forward or leading end flap on the wrapper projects into theflared jaws though the bar itself is stopped in its travel by the lipsIIIbv and |I1h of the jaws. The movement of the bar has thus beenstopped and the bar is at this time awaiting the action of a pusher toagain commence its travel, but this time the direction of travel isnormal to the previous direction of travel of the bar.

Referring first to Fig. 1 this next operation that is performed on thebar involves a pusher member generally indicated at ||9 that isinltially disposed substantially in the position diagrammaticallyillustrated in Fig. 1 where the bar can pass in front of it but whichmoves ln the direction indicated by the arrowv D, to push the bar ontothe final operations conveyor generally indicated at |20. The structureand operation of this pusher member I I9 is best shown in Figs. 6 to 8inclusive. The structure includes a pusher plate |2| that is mounted onthe lower ends of; a pair of pusher arms |22. Each pusher arm |22 issuspended on its upper end on a movable channel shaped rack |23 that issupported in a wall member |24 which in turn is screwed as at |25 ontothe portion of upstande ing wall 61 of the machine frame. |23 areadapted to slide back and forth in a direction'corresponding to theirlongitudinal dimension and along the edge of each of the rack flanges isdisposed a plurality of rack teeth |26. The racks are joined togetherby-a plate |23a.

Disposed at right angles to the length of the racks I23'is a `shaft |21(see Figs. 6 to 8) that is journalled at its opposite ends in bearingmembers |28 that are secured by means of screws |29 to the wall 61 ofthe machine frame. Mounted on this shaft |21 is a pair of pinion gears|30 havinga plurality of teeth |3| that are adapted The racks I 2 1 inthe region-between the previously men--v tioned pinionv gears |33. Thelower end ofl the verticallydisposed armN 32 is provided with aY lug`orA cam `follower that is adaptedto'ride a` cam track or 'groove in acam wheel |31 that is.- disposed on the shaft |63. This carri-tract:Ainl cam |31 provides reciprocating movement ofl thearm |32 in an upwardand downward direction in proper timed, relationship with the movementof lthecandy through.. the machine and-this movement of arm-` |32 in*turnfimparts similar recipe rocatingmovem'ent totherack |23 and henoetothetpusher plateV |2|. In this` mannerthe candy barthat-is. disposedinthe position shown'at lilo. in'lief. 9v is pushed in a'transversedirection by pusher plate .|-2| which corresponds to the directionfromright to left-in Fig, '8- onto the iinal operations conveyor.|25...V

One. embodiment'of the'flnal operations conveyor|2ll-is bestshown in-Figs. 6 to 8 inclusive and .is mountedon abaseV |33 that is supportedon...the. upright wall` Ble-fthe machine; frame. Extending.upwardlyfromithis base |33 is a 1pair of spacedsidewalls |33.Mounted-'between these Y spaced .side walls. |39 arelowerand. uppercon-Y veyor assemblies generally indicated at` |33 and |41 respectively.Thev lower conveyor assembly |fcomprises spaced shafts |52l and |53 onwhich arej'mounted drums |34 and |35. respectivelyr (see Eig. 8). A belt|46 operates over the drums |44'and |55.- The upper conveyor assembly|4| comprisesapair of spaced-shafts |41 andlon-whichsis mounted a pairof drums |33 and |53l respectively.

Bo'thllbelts fit into the grooved portions of thedrums and pulleys. As will be noted inAFi'g. 6 the 'belts |82 are spacedapart at one end a dis'l tance foorresponding to the distance betweenthe inner lcourses of side belts |69. In travelling alongthe length ofthese flap folding belts toward 'their opposite ends, they convergetoward each other. As will be noted in Fig. 8 the upper course of=eachof the flap folding belts |82 is disposed flush 'with the upper courseof the lower belt'|46. I l Y Asbest shown'in Figs. 6 and 8 mounted onthe shaft |43'in addition to drum |45 is apair of initial tueker rollers|83, one being mounted on each'side of the lower conveyor belt |46. Alsomountedl on the'shaft |43 is a Vpair of spaced apart glue applicatordiscs |84, one being mounted on each side of the lower conveyor belt|46.

'Referring to Fig. 8 a shaft |85 is journalled in thefwallsof anaperture |86 of aplate |81 that is mounted on the base |38 and a pair ofspaced intermediate glue rollers |88 disposed respectively below'tlieglue applicator discs |84 are mounted on the shaft |85. Disposed belowthe aperturev |86 in plate |81 isa corresponding aperture |89 inthebase'l38. A glue pot |90 is mounted below this aperture |89 and isvaligned therewith. Mounted on a shaft |9| that is journalledin the gluepot |90 is a primary glue applicator. roller |92 that engages theperiphery of the intermediate glue roller |88.

Disposed between shaft |43 and the side belt conveyor assemblies |63 isa final tucker assembly generallyindicated at` |93 that includes a shaft|94 upon which are mounted spaced tucker rollers |95. This shaft |94 ismounted in a frame |96 as best shown in Fig. 8, that is secured by meansof screws |91 to the appropriate machine framing parts. Mounted on theshaft |94 between the tucker rollers |95 is a drum |98. A pressurevroller |99 is mounted on a shaft 200 that is likewise journalled in theframe |96. The lower belt |46 passes over the drum |98 and the pressureroller |99r serves as a take-up roller tol take up the slack in thebelt. The belt |46 then' serves to rotate drum |98 and consequently thetucker rollers |95. 'Y

Referring now to Figs. 8,A 14 and 176 the horizontally :disposed shaft|48, upon which the drums |50 are mounted, also is provided with a pairof drums 20| that are spaced at opposite ends of the shaft. Spaced fromthis shaft |48 andA extending downwardly from each of the side framingmembers |54 of the upper belt assembly 4| is a Vbracket 202 at the lowerend of which is disposed' a v'shaft`203 that is journalled between thebrackets 202. Mountedy on this shaft 203 is a pairof'drums 204.Operating about each of th'edrums 204 and the corresponding drum 20|is'a ap belt 205 that slopes downwardly from the' drum |50'to drum'204.dAs shown in' Figs. 6 to 8 inclusive a final exit conveyor generallyVindicated at 206 is disposed at the discharge end of the conveyor unit|20 and this exit conveyor 206 includes a belt 201 that' operates at oneend of the conveyor about the drum |49 (see Fig. 8). The .drive for thecomplete wrapping machine is provided vthrough a plurality of shaftshaving chain and sprocket drives and gear drives. Re-

|08 is provided with a main drive gear 208 Ythat is operativelyconnected through a series of gears to a suitable primeV mover, such asan electric motor 319 (see Fig. 34). MountedY on the shaft V|88 is asprocket wheel 209 which is keyed to the shaft |08 so as to rotatetherewith. `The sprocket chain indicated in broken lines at 2|0 in Fig.9 operates about this Sprocket whee1209 and about sprocket wheels 93 andI3 which were previously described. An idler take-up sprocket 2|| ismounted on'an idler arm 2|2 that in turn is secured to upright plate|62. Thus as the motor drives the shaft |08 through gear 208v thesprocket wheel 209 drives sprocket chain 2 0 and hence rotates sprocketwheels 93 and I3, therebyl rotating pull discs 63 and operating beltconveyor 64.- l

The rotation of shaft |08 also rotates the cam |31 (see Fig. 7) so as tooperate the pusher mechanism that includes the pusher plate |2|.

Also mounted on the shaft |08 is a spiral gear 2|3 and directly belowthisspiral vgear 2|3 is a stub shaft 2|4 that is journalled in a wall2|5 that extends outwardly from the wall 68. Mounted on this stub shaft2|4 is a gear 2| 6 that meshes with spiral gear 2 |3. Also mounted onshaft 2 |4 is a sprocket wheel 2 |1 that is pinned to the shaft torotate therewith. A stub shaft 2 I8 is mounted on the upright plate |62and mounted on this stub shaft 2|8 is a sprocket Wheel 2|9. VA sprocket`chain 220 operates about this sprocket wheel 2 9 and the previouslymentioned sprocket wheel 2|1. Also mounted on the shaft 2|8 is a gear22| which in turn meshes with a gear 222 that is mounted on the shaft|85. This gear 222 in turn meshes with a gear 223 that is 4mounted onthe shaft |43. Thus as the shaft |08 rotates under the influence of themotor drive it operates the sprocket chain 220 so as torotate the system`of gears 22|, 222 and 223. TheV latter gear 2723 is keyed to shaft |43so as to operate the lower belt |46. Gear 222 in turn meshes` with gear|92a (Fig. 8) on shaft |9| to rotate glue applicator roller |92. y

Again referring to Fig. '7 a sprocket wheel 224 is mounted on the shaft|42. Disposed adjacent to shaft |42 and journalled` between walls |39 isa shaft 225 on which is mounted a sprocket wheel 226. Below shafts |42and 225 and supported on an adjustable bracket 221 is a stub shaft 228.Mounted on this shaft 228 is an idler take-up sprocket 229. Mounted onshaft |41 of the upper conveyor assembly |4| is a sprocket wheel 230that is keyed to the shaft |41 to rotate therewith. Mounted at the otherend of the final operations conveyor assembly |20 is a stub shaft 23| onwhich is mounted a sprocket wheel 232 and a gear 232-av that meshes withgear 2|9. Adjacent to shaft 23| is an idler stub shaft 233 on which ismounted an idler sprocket wheel 234 and above this shaft 233 is a stubshaft 235 on which is mounted a sprocket wheel 236. Operating aboutsprocket wheels 224, 229, 226,234, 232, 236 'and 230 is a sprocket chain231 which is powered by rotation of sprocket wheel 232. By virtue of therotation of the sprocket wheel 230 the upper conveyor belt 5| is causedto move.

As best sho-wn in Figs. 6, 7 and 13 an upstanding shaft 238 isjournalled in the base portion |3811. and mounted on the upper end ofthis shaft 238 is a bevelledgear 239 that meshes with a bevelled gear240 (see Fig. 13) mounted on shaft `225. Also mounted on this shaft 238is a sprocket -Wheel 24|. Mounted on the shaft |64 (see Figs.
